Abstract:
Objective Optimizing the preparation technology of Red buttock ointment,by exploring the best extraction conditions of the alkannin,radix arnebiae seu lithospermi polysaccharides and so on.Methods Selecting radix arnebiae seu lithospermi 1kg and using orthogonal experiment to explore the best extraction conditions.Naphtho-quinone pigment chemicals were extracted by reflux extraction method;ethanol and paraffin wax were chosen as the composite solvent.Radix arnebiae seu lithospermi polysaccharide was extracted by water decocting,which to observe the rationality of process.Results The best extraction condition is A3 B2 C1 D1 , including section A:ethanol was 20 times the quality of medicinal materials (select radix arnebiae seu lithospermi 1kg and ethanol 20kg),section B:the amount of paraffin was 5% of ethanol(select radix arnebiae seu lithospermi 1kg and paraffin 1 kg),section C:Boiling water was 20 times the quality of medicinal materials,section D:the boiling time was 2h.Conclusion The more practical production process conditions:Ethanol was 10 times the quality of medicinal materials,and the amount of paraffin was 5%of ethanol.Boiling water was 10 times the quality of medicinal materials,and the boiling time was 1 h.This method is economic, simple, reasonable, stable, reproducible and easy to operation.Red buttock ointment obtained by this method possesses of excellent quality,good performance and superior effect.
